Long story not so short, I work at a somewhat popular bar/music venue in Baltimore and one of my fellow employees came into the possession of an arcade machine called Quartet. It's a terrible, terrible game, and our manager said 'wouldn't it be awesome if we could play that old school ninja turtles on it? That got me thinking about emulators and after days of searching the internet I wound up here. After reading thru dozens of faqs, convos and advice threads I feel like I could turn this crappy arcade game into a great Mame cab. I still have a few questions though..
The arcade cabinet is a bit on the thin side for a game with 4 players.

But our goal is to be able to play the 4 player game such as TMNT on it as well as 2 player fighting games such as mortal kombat 1-3, street fighters II series and hopefully the marvel vs capcom series of games. that would mean that players 1-2 have 6 buttons each and players 3-4 have 4.
I will be going in to do the measurements of the control panel tonight or tomorrow but as it is right now, I do not think I'd have enough room to give players 1 and 2 6 buttons without making it more cramped than it already is.
So I only could think of 3 solutions. First just drilling the new holes for the extra buttons on the existing panel and hoping that only tiny people want to play Simpsons.
Second option was making the control panel wider, which would mean i'd have to build extra support for the eventual drunk person who would mash down on the buttons trying to do some super combo.
or slide the 3-4 player area higher and remove the grey sides of the arcade cabinet shown here

which would give players 3-4 more room. If I do this then I would have to completely replace the front control panel and I would have to put an LCD monitor inside the cab, since there would be no room for anything else. And I've spent the past few days playing mame games on my 40" LCD TV and I really don't think it's that bad of a picture so I'm sure drunkpeople won't mind. Anyone have any other thoughts?
My other question is how in the world am i supposed to turn the monitor on? I understand wiring a power pushbutton to the back of the cab so I can power on the PC, but I can't figure out how I would do the same for a monitor
Since I am going with either an LCD monitor or a television If there is anyone in the Baltimore area who would like the monitor from this arcade machine, please let me know and you can gladly take it. I believe it's in great condition, as we've played this crappy arcade game on it multiple times and have seen no issues. And if you'd like to give me a hand I'd be happy for the help
